Honda CRF125F

The Honda CRF125F was introduced for the model year 2014. It replaced the long running CRF/XR80 (similar 17"/14" wheel size) and CRF/XR100 (big wheel, similar 19"/16" wheel size). It received a completely new motor and body work similar to the full race CRF big bikes. Some of the part look similar to the older CRF/XR80/100, but for the most part it is an entirely new bike. While it is manufactured in China, quality is worlds better than any other Chinese bike and the equal of any Japanese manufactured playbike.
